PUBLIC HEALTH ASSESSMENT

ANNIE CREEK MINE TAILINGS
(RELIANCE TAILINGS)
LEADE, LAWRENCE COUNTY, SOUTH DAKOTA


CONCLUSIONS

  1. Based on the information currently available, ATSDR concluded that the Annie Creek Mine Tailings Site represents a no apparent health hazard since the data do not indicate exposure to contaminants at levels of health concern are occurring.
  2. There is potential for vacationers and seasonal residents to be exposed to arsenic in surface water, groundwater, sediments, and biota. However, based on the arsenic concentrations reported in each of these media, no adverse health effects are expected to occur in individuals (seasonal residents or vacationers) from ingestion of these media on a seasonal basis. Dermal contact with arsenic contaminated surface water or sediments is not considered a significant pathway of exposure since absorption of arsenic thorough the skin would be minimal.
  3. There were no adverse health problems reported in regard to the arsenic contamination in Annie or Spearfish Creek.
  4. The Spearfish municipal water system was not and is not currently impacted bycontamination in Annie Creek.



RECOMMENDATIONS

Based on the data reviewed, ATSDR does not recommend any further action at this time.

HEALTH ACTIVITIES RECOMMENDATION PANEL RECOMMENDATIONS

    In order, to determine if public health actions are needed, ATSDR's Health ActivitiesRecommendation Panel (HARP) evaluated the data and information developed in the AnnieCreek Mine Tailings Public Health Assessment. The HARP recommended that the communitybe provided additional information concerning the potential exposure to arsenic from potablewater and fish.

Public Health Action Plan

Actions Undertaken

  1. ATSDR recommended that groundwater in the alluvium and deep aquifers be monitored todetermine if there is an impact of Reliance Tailings on the water that supplies private wells alongSpearfish Creek. An inventory was conducted to determine the status of residential propertiesaround the Reliance Tailing Site (vacation versus permanent residence); all domestic wells wereinventoried (location, potential use; screened interval; and water quality); groundwater in Annie and Spearfish Creek was monitored.

  2. ATSDR recommended that the total arsenic concentration of edible species of fish from Annieand Spearfish Creek be monitored to ensure the quality of fish was safe for the recreational consumer. Fish were sampled in Annie and Spearfish Creek.

  3. A nontime critical removal action for Annie Creek Mine Tailings Site was initiated by thepotentially responsible parties. The removal action included covering exposed areas of arsenic contaminated tailings with clean soil, regenerating the cover, establishing drainage controls todivert surface water runoff, and instituting controls which may include deed and accessrestrictions, land use limitations, groundwater restrictions, surface water monitoring, and public information programs to address potential human health risks posed by the site (15).

Actions Planned

  1. ATSDR recommends no further actions at this time.
